MINNEAPOLIS (AP) — The Hennepin County sheriff’s office is warning people to be careful on the ice after three men broke through the ice on Twin Cities lakes.

On Saturday, the sheriff’s office was called when a man wound up in the water after his ice boat broke through the ice on Lake Minnetonka near Big Island.

The Deephaven man was able to make it to shore on his own. He was not hurt.

Two men also broke through the ice Saturday on Lake Riley in Eden Prairie, on the border of Carver and Hennepin counties. The men were not hurt.

Hennepin County authorities say ice thickness varies because of the warm weather and freezing and thawing that has taken place over the last several weeks.
